Hi,

first you should define how your web application is layouted, are you using single-page with dynamically loaded/generated content (use GWT History mechanisms https://developers.google.com/web-toolkit/doc/latest/DevGuideCodingBasicsHistory). Or perhaps you are using multi-page layout and GWT as a supporting script same on all pages, then you should be fine with standard HTML way with a single module. Or you may have multiple pages with different behavior, then multiple modules may be a solution but it could generate a lot of shared code downloaded multiple times, I would suggest using some form of code splitting (https://developers.google.com/web-toolkit/doc/latest/DevGuideCodeSplitting?hl=en), each code fragment may be initialized based on URL or JS call directed to GWT through JSNI (https://developers.google.com/web-toolkit/doc/latest/DevGuideCodingBasicsJSNI?hl=en). If you are just trying to open another page by script use http://google-web-toolkit.googlecode.com/svn/javadoc/2.5/com/google/gwt/user/client/Window.Location.html replace function.

Hope it helps and that I understood your problem.
